The crystal structure of the 1:2 dihydrate compound of chloranilic acid (systematic name: 2,5-di­chloro-3,6-dihy­droxy-1,4-benzo­quinone) with 2-carb­oxy­pyridine (another common name: picolinic acid; systematic name: pyridine-2-carb­oxy­lic acid), namely, 2C6H5.5NO20.5+·C6HCl2O4−·2H2O, (I), has been determined at 180 K, and the structure of the 1:2 dihydrate compound of chloranilic acid with 2-carb­oxy­quinoline (another common name: quinaldic acid; systematic name: quinoline-2-carb­oxy­lic acid), namely, 2C10H7NO2·C6H2Cl2O4·2H2O, (II), has been redetermined at 200 K. This determination presents a higher precision crystal structure than the previously published structure [Marfo-Owusu & Thompson (2014[Marfo-Owusu, E. & Thompson, A. L. (2014). X-ray Struct. Anal. Online, 30, 55-56.]). X-ray Struct. Anal. Online, 30, 55–56]. Compound (I) was analysed as a disordered structure over two states, viz. salt and co-crystal. The salt is bis­(2-carb­oxy­pyridinium) chloranilate dihydrate, 2C6H6NO2+·C6Cl2O42−·2H2O, and the co-crystal is bis­(pyridinium-2-carboxyl­ate) chloranilic acid dihydrate, 2C6H5NO2·C6H2Cl2O4·2H2O, including zwitterionic 2-carb­oxy­pyridine. In both salt and co-crystal, the water mol­ecule links the chloranilic acid and 2-carb­oxy­pyridine mol­ecules through O—H⋯O and N—H⋯O hydrogen bonds. The 2-carb­oxy­pyridine mol­ecules are connected into a head-to-head inversion dimer by a short O—H⋯O hydrogen bond, in which the H atom is disordered over two positions. Compound (II) is a 1:2 dihydrate co-crystal of chloranilic acid and zwitterionic 2-carb­oxy­quinoline. The water mol­ecule links the chloranilic acid and 2-carb­oxy­quinoline mol­ecules through O—H⋯O hydrogen bonds. The 2-carb­oxy­quinoline mol­ecules are connected into a head-to-tail inversion dimer by a pair of N—H⋯O hydrogen bonds.

1. Chemical context

Chloranilic acid, a dibasic acid with hydrogen-bond donor as well as acceptor groups, appears particularly attractive as a template for generating tightly bound self-assemblies with various pyridine derivatives as well as being a model compound for investigating hydrogen-transfer motions in O—H⋯N and N—H⋯O hydrogen-bond systems (Zaman et al., 2004[Zaman, Md. B., Udachin, K. A. & Ripmeester, J. A. (2004). Cryst. Growth Des. 4, 585-589.]; Molčanov & Kojić-Prodić, 2010[Molčanov, K. & Kojić-Prodić, B. (2010). CrystEngComm, 12, 925-939.]; Seliger et al., 2009[Seliger, J., Žagar, V., Gotoh, K., Ishida, H., Konnai, A., Amino, D. & Asaji, T. (2009). Phys. Chem. Chem. Phys. 11, 2281-2286.]; Asaji et al. 2010[Asaji, T., Seliger, J., Žagar, V. & Ishida, H. (2010). Magn. Reson. Chem. 48, 531-536.]). Previously, we have prepared three 1:1 compounds of chloranilic acid with 2-, 3- and 4-carb­oxy­pyridine and analysed the crystal structures in order to extend our study on D—H⋯A hydrogen bonding (D = N, O or C; A = N, O or Cl) in chloranilic acid–substituted pyridine systems (Gotoh et al., 2006[Gotoh, K., Tabuchi, Y., Akashi, H. & Ishida, H. (2006). Acta Cryst. E62, o4420-o4421.], 2009[Gotoh, K., Nagoshi, H. & Ishida, H. (2009). Acta Cryst. E65, o614.]; Tabuchi et al., 2005[Tabuchi, Y., Takahashi, A., Gotoh, K., Akashi, H. & Ishida, H. (2005). Acta Cryst. E61, o4215-o4217.]). In the present study, we have prepared a 1:2 compound of chloranilic acid with 2-carb­oxy­pyridine and also redetermined the structure of a 1:2 compound of chloranilic acid with 2-carb­oxy­quinoline with higher precision than previously reported structure [Marfo-Owusu & Thompson, 2014[Marfo-Owusu, E. & Thompson, A. L. (2014). X-ray Struct. Anal. Online, 30, 55-56.]; although the title and text in this reference refer to the 1:1 adduct of chloranilic acid with 2-carb­oxy­qulinone, the reported structure is the 1:2 compound, the same as the present compound (II)]. The crystal structure of the anhydrous 1:2 compound of chloranilic acid with 2-carb­oxy­quinoline was also reported by Marfo-Owusu & Thompson (2016[Marfo-Owusu, E. & Thompson, A. L. (2016). X-ray Struct. Anal. Online, 32, 49-50.]).

2. Structural commentary

Compound (I)[link] (Fig. 1[link]) crystallizes with one-half of a chloranilic acid mol­ecule, which is located on an inversion centre, one 2-carb­oxy­pyridine mol­ecule and one water mol­ecule in the asymmetric unit. In the crystal, the water mol­ecule is disordered over two sites with equal occupancies of 0.5. The occupancies of the H atoms in the chloranilic acid mol­ecule and the carb­oxy group of the 2-carb­oxy­pyridine mol­ecule are also 0.5. The compound is, therefore, considered to be a disordered state over two forms, viz. bis­(2-carb­oxy­pyridinium) chloranilate dihydrate, (A), and bis­(pyridinium-2-carboxyl­ate) chloranilic acid dihydrate, (B), as shown in the scheme and Fig. 2[link]. In form (A), the water mol­ecule acts as one N—H⋯O hydrogen-bond acceptor and two O—H⋯O hydrogen-bond donors (N1—H1⋯O5A, O5A—O9A⋯O4ii and O5A—H10A⋯O2; symmetry code as in Table 1[link]), while in form (B), the water mol­ecule acts as the acceptor of N—H⋯O and O—H⋯O hydrogen bonds, and as two O—H⋯O hydrogen-bond donors (N1—H1⋯O5B, O2—H2⋯O5B, O5B—H9B⋯O4ii and O5B—H10B⋯O1iii; Table 1[link]). The dihedral angle between the pyridine ring and the carb­oxy plane in the base mol­ecule is 23.32 (15)°.

The asymmetric unit of compound (II)[link] consists of one-half of a chloranilic acid mol­ecule, which is located on an inversion centre, one 2-carb­oxy­quinoline mol­ecule and one water mol­ecule. In the crystal, the 2-carb­oxy­quinoline mol­ecule is in a twitterionic form and no acid–base inter­action involving H-atom transfer between chloranilic acid and 2-carb­oxy­quinoline is observed (Fig. 3[link]). The dihedral angle between the quinoline ring system and the carboxyl­ate plane in the base mol­ecule is 20.84 (19)°. The water mol­ecule acts as an O—H⋯O hydrogen-bonding bridge between the chloranilic and 2-carb­oxy­quinoline mol­ecules (O2—H2⋯O5 and O5—H3⋯O4; Table 2[link]).

3. Supra­molecular features

In the crystal of compound (I)[link], the 2-carb­oxy­pyridine mol­ecules, which are related by an inversion centre, are linked into a head-to-head dimer via a short O—H⋯O hydrogen bond, in which the H atom is disordered over two sites (O3—H3⋯O3i; Table 1[link]), as observed in pyridinium-2-carb­oxy­lic acid pyridinium-2-carboxyl­ate perchlorate (Wang et al., 2015[Wang, B.-Q., Yan, H.-B., Huang, Z.-Q., Zhang, Y.-H. & Sun, J. (2015). Acta Cryst. C71, 247-251.]). The three components are linked via the above-mentioned O—H⋯O and N—H⋯O hydrogen bonds together with weak C—H⋯Cl and C—H⋯O hydrogen bonds (C8—H8⋯Cl1iii and C8—H8⋯O1iii; Table 1[link]), forming a layer parallel to the ab plane (Fig. 4[link]). In the layer, the chloranilic acid rings are stacked along the b axis through a π–π inter­action [centroid–centroid distance = 3.6851 (7) Å and inter­planar spacing = 3.2118 (4) Å]. The pyridine rings are also stacked along the b axis through a π–π inter­action [centroid–centroid distance = 3.6851 (7) Å and inter­planar spacing = 3.4787 (5) Å]. Between the layers, a short Cl⋯Cl contact is observed [Cl1⋯Cl1v = 3.3717 (5) Å; symmetry code: (v) −x + 1, y − [{1\over 2}], −z + [{1\over 2}]].

In the crystal of (II)[link], two adjacent 2-carb­oxy­quinoline mol­ecules, which are related by an inversion centre, form a head-to-tail dimer via a pair of N—H⋯O hydrogen bonds (N—H1⋯O3i; symmetry code as in Table 2[link]). The dimers are stacked in a column along the a axis through a weak π–π inter­action between the N1/C4–C7/C12 and C7–C12 rings with a centroid–centroid distance of 3.9184 (10) Å. The water mol­ecule links the stacked base mol­ecules related by translation along a via O—H⋯O hydrogen bonds [O5—H3⋯O4 and O5—H4⋯O4ii; Table 2[link]] and also links the acid mol­ecule and the two base mol­ecules via O—H⋯O hydrogen bonds, forming a layer structure parallel to (0[\overline{1}]1) as shown in Fig. 5[link]. No significant short contact between the acid mol­ecules in the layer is observed. Between the layers, a bifurcated C—H⋯(O, O) hydrogen bond (C6—H6⋯O1iii and C6—H6⋯O5iv; Table 2[link]) is observed, through which the 2-carboxy­quinoline mol­ecule is weakly linked with the chloranilic acid and water mol­ecules.

4. Database survey

A search of the Cambridge Structural Database (Version 5.38, last update May 2017; Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]) for organic co-crystals of pyridinium-2-carboxyl­ate (twitterionic form) gave six structures. For organic co-crystals of quinolinium-2-carboxyl­ate (twitterionic form), eight structures were found.

5. Synthesis and crystallization

Single crystals of compound (I)[link] were obtained by slow evaporation of an aceto­nitrile solution (200 ml) of chloranilic acid (250 mg) with 2-carb­oxy­pridine (310 mg) at room temperature. Single crystals of compound (II)[link] were obtained by slow evaporation from a methanol solution (150 ml) of chloranilic acid (310 mg) with 2-carb­oxy­quinoline (520 mg) at room temperature.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3[link]. The water mol­ecule in compound (I)[link] was found to be disordered over two sites in a difference-Fourier map. The occupancies were refined to 0.52 (2) and 0.48 (2) and then they were fixed at 0.5. The H atom in the carb­oxy group of the base mol­ecule was also found in a difference-Fourier map to be disordered between the adjacent carb­oxy groups, which are related by an inversion centre, and the occupancy was set to be 0.5. Since the N-bound H atom refined reasonably with an occupancy of 1, the occupancy of the H atom of the acid mol­ecule was set to be 0.5 to balance the total charge of the compound. All other H atoms were found in a difference-Fourier map. The N-bound H atom was refined freely, while the positions of O-bound H atoms were refined, with O—H = 0.84 (2) Å and Uiso(H) = 1.5Ueq(O). For the water H atoms, distant restraints of H⋯H = 1.37 (4) Å were also applied. C-bound H atoms were positioned geometrically (C—H = 0.95 Å) and were treated as riding with Uiso(H) = 1.2Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
